In one aspect of the invention, a wayfinding device is described that is specifically designed for hospital environments. This device is equipped with a central OLED display that shows patient-specific information. This information includes the name of the attending physician, the room number, the estimated time of the appointments, and directions to the destination within the hospital.The device offers dynamic and up-to-date guidance, whereby routes are automatically adjusted based on changes in the hospital, such as rescheduled appointments or altered routes due to, for example, temporary construction activities.35 BE2024 / 5820 5 The device contains a haptic feedback motor, which guides the user via vibrations. This is particularly useful for patients with visual impairments or in busy, noisy environments where visual and auditory signals are difficult to distinguish. The haptic feedback ensures that the patient can intuitively follow the correct direction without having to constantly look at the screen. This contributes to a stress-free experience, because the patient feels safe and secure while navigating through the hospital. Another important feature of the device is the integration of a Bluetooth Low Energy (BLE) module. This module makes it possible to determine the location of the patient in relation to BLE beacons that are strategically placed in the hospital.This allows the device to offer a GPS-like navigation experience without the need for a smartphone or a complex mobile application. The directions on the OLED screen are automatically updated as the patient moves through the hospital, ensuring seamless and efficient navigation. The help button on the device provides a direct line of communication with the doctor's office or a secretary. This enables the patient to ask questions or request help with a single press of the button, without requiring technological knowledge. Communication can be either visual or auditory, depending on the patient's preferences and needs. This significantly increases the accessibility and user-friendliness of the device. The device is designed to receive real-time updates from the hospital information system. This means that changes in the appointment location or time are immediately transmitted to the device, ensuring that the patient is always served with the most up-to-date information.This prevents confusion and ensures that the patient arrives at the correct location on time and without problems. 30 The combination of these functions makes the wayfinding device an essential tool for improving the patient experience in hospitals. It not only offers an efficient and stress-free way to navigate through the hospital, but also improves the overall efficiency of the hospital by minimizing missed appointments and optimizing patient flow. This aspect of the invention offers a clear solution to the challenges associated with traditional navigation methods within complex hospital environments. BE2024 / 5820 6 In a preferred configuration, the wayfinding device is equipped with a system for receiving real-time updates from the hospital information system. This system enables the device to immediately communicate and adjust changes in the route or time. This preferred configuration offers significant benefits for the patient, such as a reduction in navigation errors.The ability to receive up-to-date information allows the patient to find their way around the hospital with more certainty and less stress. Preferences for the configuration of the update system may vary, but preferably include a wide range of operational frequencies for receiving updates. The frequency can preferably be between 1 and 10 seconds, more preferably between 2 and 8 seconds, even more preferably between 3 and 7 seconds, even more preferably between 4 and 6 seconds, and most preferably every 5 seconds. This frequency ensures that the information provided to the patient is always up-to-date, without excessively burdening the system. Furthermore, the system can preferably use a secure connection to ensure that data transfer is reliable and secure. This can preferably be achieved by using encryption protocols such as SSL or TLS.20 The device can preferably also include a buffer to handle temporary interruptions in the connection, thereby ensuring the continuity of service to the patient.Thanks to these real-time updates, the device can inform the patient exactly about the expected arrival time at the doctor. This reduces the uncertainty and stress associated with navigating in a hospital environment. Furthermore, by providing the patient with up-to-date information, the device can help reduce time pressure, which contributes to a more relaxed experience for the patient. The ability to respond more quickly to changes in scheduling or location is therefore an important advantage of this preferred configuration, thereby improving the overall efficiency and effectiveness of the wayfinding device. BE2024 / 5820 7 In a preferred configuration, the wayfinding device includes various vibration patterns that can be variable to indicate changes in direction. This offers an intuitive navigation experience for users who may not be able to use visual aids or who are in environments where visual cues are difficult to interpret.The vibration patterns can vary in intensity and frequency in a preferred configuration, so that every change of direction can be clearly distinguished. Optionally, these vibration patterns can be tailored to the patient's personal preferences, creating a personalized navigation experience. In a further preferred configuration, the device can also be equipped with a function that allows the user to choose between different vibration modes, such as continuous or intermittent vibrations, depending on their comfort and needs. In a more preferred configuration, the intensity of the vibrations can be set within a range of 1 to 10, where 1 represents a very light vibration and 10 a very strong vibration. This setting can be further optimized with intermediate steps such as 2, 3, 4, 5, 6, 7, 8, and 9 to offer the user a wide range of options for an optimal experience.In an even more advanced preferred configuration, the device can also provide feedback on the proximity of the destination by increasing the frequency of the vibrations as the user gets closer to their destination. This can help the user to be aware of their progress and to gain confidence in the navigation. Optionally, the device can also include a function that allows the user to choose to receive auditory signals in addition to the haptic feedback, for an even richer navigation experience. These features contribute to the user-friendliness and accessibility of the wayfinding device, making it particularly suitable for use in complex environments such as hospitals, where clear and reliable navigation is essential for the well-being of the patients. BE2024 / 5820 8 In a preferred configuration, the wayfinding device uses an OLED screen that displays patient-specific information.This screen is preferably designed to significantly reduce the chance of missed appointments by providing detailed information about the way to the destinations and any changes to the doctor's expected schedule. The OLED screen can optionally display various types of information, such as text, symbols, and graphic elements, which increases readability and accessibility for the patient. Preferably, the OLED screen can have a resolution ranging from 128x64 to 256x128 pixels, with a resolution of 128x128 pixels10 being preferred for an optimal balance between detail and energy consumption. In a further preferred configuration, the screen brightness can be adjustable, ranging from 100 to 500 nits, with a brightness of 300 nits being preferred to ensure that information remains clearly visible under various lighting conditions.15 The use of an OLED screen offers more advantages than traditional LCD screens, as OLED screens preferably have a higher contrast ratio and offer wider viewing angles.This makes it easier for patients to read the information, even when the device is held at an angle. Furthermore, in a preferred version, the OLED screen can be more energy-efficient, which contributes to a longer battery life of the device. In another preferred version, the OLED screen can also contain interactive elements, such as touch functionality, allowing patients to navigate through different layers of information. This can further improve the user experience by giving the patient more control over the displayed information. The screen can also optionally be capable of displaying colors, which increases visual appeal and the ability to encode information based on color. In summary, the preferred version of the wayfinding device, by using an OLED screen, offers an effective and efficient way to communicate patient-specific information, which contributes to an improved patient experience and a reduction in missed appointments within the hospital environment.BE2024 / 5820 9 In a preferred configuration, the wayfinding device automatically adjusts navigation directions based on the patient's current location. This can significantly improve the accuracy and reliability of the description, as the patient receives the most relevant and current directions at all times. To this end, the device can use a combination of 5 technologies, including BLE beacons strategically placed in the hospital to determine the patient's location. Preferably, the device connects to multiple BLE beacons simultaneously, enabling accurate triangulation of the patient's position. This system can be further refined by using additional sensors, such as gyroscopes and accelerometers, which can track the patient's movement in real-time. In this way, the device can determine not only the patient's current location but also the direction and speed of movement.15 The OLED display on the device can preferably be configured to provide directions in various formats, such as text, icons, or even simple maps. This offers flexibility to patients with different preferences or needs. Additionally, in a more preferred configuration, the device can adapt the directions based on the time of the appointment,20 taking into account the average speed of the patients and any delays in the hospital. The wayfinding device can also optionally be equipped with a function that warns the patient of obstacles or temporary closures within the hospital,25 by using real-time updates from the hospital information system. This ensures that the patient always follows the most efficient route, even in the event of unexpected changes in the hospital environment. 30 By integrating these advanced functions, the device can not only improve navigation, but also contribute to increased patient satisfaction and a more efficient flow within the hospital.These configurations emphasize the versatility and adaptability of the device, making it a valuable addition to existing wayfinding solutions in healthcare. BE2024 / 5820 10 In a preferred configuration, the wayfinding device includes an auditory alert that informs the patient about approaching their destination within the hospital. This auditory alert can optionally be configured to use different sound patterns or volumes, depending on the patient's preferences or needs. It is preferably possible to personalize the auditory alert, so that it contains a recognizable sound or even a spoken message specific to the patient. This can further increase patient confidence, as they feel more at ease with a familiar sound or voice. 10 The auditory alert is preferably designed to function in various environmental conditions, such as busy or quiet hospital wards, and can therefore optionally have variable sound levels.The sound levels can preferably be set between 30 and 90 decibels, more preferably between 40 and 80 decibels, more preferably between 50 and 70 decibels, more preferably between 15, 55 and 65 decibels, and most preferably between 60 and 65 decibels. This flexibility ensures that the warning remains audible without being a nuisance to the patient or others in the vicinity. In a preferred implementation, the auditory alert can also be combined with other feedback mechanisms, such as visual cues on the OLED display or haptic signals, to provide a multimodal approach that improves the patient's navigation experience. This combined approach can be particularly useful for patients with specific sensory impairments, allowing them to be informed and supported in different ways. Furthermore, in a preferred implementation, the auditory alert can be synchronized with the real-time updates of the hospital information system.This means that if there are changes in the patient's route or destination, the audio alert can be adjusted accordingly to provide the patient with current information. This dynamic adjustment contributes to increased awareness and confidence of the patient, as they are continuously guided with the most relevant and up-to-date information during their journey through the hospital. 35 BE2024 / 5820 11 In a preferred version, the wayfinding device includes a built-in assistance function that optionally offers the possibility for direct communication with hospital staff. This function preferably increases patient confidence by providing a direct line of communication, which can be particularly important in stressful or confusing situations in which the patient finds themselves.5 The assistance function can preferably be activated by a simple press of a button, which is located in an easily accessible location on the device.This button can optionally be provided with an intuitive marking, such as a recognizable icon or a tactile indication, to improve accessibility for all users, including those with visual impairments. Upon activation of the assistive function, the device can preferably establish a connection with the hospital network, enabling direct communication with relevant hospital staff, such as a nurse or an administrative employee. Optionally, this communication can take place both visually and audibly, depending on the patient's preferences and needs. The system can also preferably be equipped with a real-time translation function, which can be useful in multicultural environments where language barriers may pose a problem. This function can optionally use predefined language options or an automatic translation algorithm to ensure that patients and hospital staff understand each other well.The built-in assistance function can be further optimized by equipping the device with a feedback mechanism that informs the patient about the status of the connections and the estimated time to response. This mechanism can preferably use both visual and haptic signals to reassure the patient that help is on the way. In an even further preferred implementation, the assistance function can be integrated with the patient's electronic medical record, allowing hospital staff quick access to relevant information and enabling them to respond adequately to the patient's needs. This integration can optionally take place via a secure connection to ensure the privacy and security of the patient data. BE2024 / 5820 12 In one aspect of the invention, it concerns a wayfinding device designed to guide patients in a hospital setting to their designated destination in an efficient and user-friendly manner. This device, hereinafter referred to as the wayfinding device, is equipped with a central OLED display that shows patient-specific information.This information includes the name of the attending physician, the room number, the estimated time of the appointment, and directions to the destination. One of the key advantages of this device is the ability to immediately update the displayed information upon changes in the appointment location or time. This ensures that patients always receive the most up-to-date route and appointment information, thereby preventing possible confusion or missed appointments. The device uses a Bluetooth Low Energy (BLE) module that continuously communicates with BLE beacons strategically placed within the hospital. This technology enables the device to accurately determine the patient's current location and adjust directions on the OLED screen accordingly. As a result, patients experience GPS-like navigation without needing to use a smartphone or complex mobile application. Another important aspect of the wayfinding device is the integration of a haptic feedback motor.This motor provides vibration feedback to the patient, which is particularly useful in situations where visual cues are insufficient, such as in busy or noisy environments. This haptic feedback can also be adapted to the patient's preferences, whereby the intensity and frequency of the vibrations are variable. In a further configuration, the intensity of the haptic feedback can vary from a low vibration, which is almost imperceptible, to a high vibration that is clearly felt, depending on the patient's needs. The device is also equipped with a help button, which allows patients to come into direct contact with the doctor's office or a secretary with a single press of the button. This function is designed to facilitate communication and ensure that patient questions are answered quickly. Communication can be either visual or auditory, depending on the patient's preferences and needs.35 BE2024 / 5820 13 An additional benefit of the wayfinding device is the ability to receive real-time updates from the hospital information system.This means that with every change of appointment location or time, the guidance can be adjusted immediately. This functionality guarantees that the patient is always served with the most up-to-date and relevant information, without confusion arising from sudden changes. This contributes to a smooth flow of patients within the hospital and increases the efficiency of healthcare staff. In a further implementation, the device can be configured to display different levels of information based on the patient's privacy settings. For example, some patients may choose to receive only the necessary route information, while others may wish to see more detailed appointment details. The device can be adapted to meet these different preferences, thereby offering a flexible and personalized experience for every user. In summary, the wayfinding device offers an innovative and patient-friendly solution for navigation in hospitals.Through the combination of visual and haptic guidance, coupled with a help function and real-time updates, the device enables patients to move easily and safely to their destination, while improving the efficiency of hospital staff. In a preferred implementation form, the wayfinding device includes a real-time update function, enabling the device to provide current information to the user. This aspect of the invention is particularly advantageous in hospital environments where conditions can change rapidly, such as changes in appointment locations or times. For example, the device can connect to the hospital information system to immediately implement changes and communicate them to the patient via the OLED display. This real-time update mechanism can optionally be configured to support different update frequencies, depending on the specific needs of the hospital.Preferably, updates can take place at intervals of 5 to 30 minutes, more preferably between 10 and 20 minutes, and even more preferably every 15 minutes. This ensures that the patient always has access to the most up-to-date information, thereby significantly reducing the risk of miscommunication or deviations from the planned schedule. In addition, in a more preferred configuration, the device can offer a buffer period during which it informs the patient of impending changes before they actually take place. This buffer period can preferably vary from 1 to 5 minutes, more preferably between 2 and 4 minutes, and even more preferably 3 minutes, giving the patient sufficient time to adapt to the new information. In another preferred configuration, the device can provide an auditory warning when an important update is received. This auditory warning can optionally be adjusted in terms of volume and pitch, making it suitable for various patient groups, including those with hearing impairments.This offers an extra layer of assurance that the information effectively reaches the patient, regardless of their individual needs or limitations. By incorporating this real-time update functionality into the design of the wayfinding device, not only is the accuracy of appointments improved, but overall patient satisfaction and efficiency within the hospital are also increased. In a preferred configuration, the wayfinding device includes a loudspeaker that provides auditory alerts, allowing patients to know immediately when they have reached their designated location without checking the OLED screen. This aspect of the invention offers a significant improvement to the navigation experience for the user. The loudspeaker is preferably positioned so that the sound is clearly audible, even in impressive and noisy environments such as hospitals. Optionally, the loudspeaker can produce different types of sounds or tones to distinguish 25 different types of notifications, such as reaching the destination or approaching an important node within the route.Preferably, the loudspeaker volume can be adjusted to the user's preferences or environmental conditions, with a range of, for example, 50 to 80 decibels. More preferably, the volume lies between 55 and 75 decibels, even more preferably between 60 and 70 decibels, and most preferably between 62 and 68 decibels. This ensures that the warnings are audible without being disturbing to the user or others in the vicinity. 35 BE2024 / 5820 15 In a further preferred configuration, the loudspeaker can be programmed to provide voice notifications, allowing the patient to receive additional instructions or confirmations. This can be particularly useful for patients with visual impairments who may not be able to follow the visual cues on the OLED screen. By combining auditory signals with visual and haptic feedback,5 the device offers a multimodal approach to navigation, which further enhances accessibility and user-friendliness.The integration of a loudspeaker into the wayfinding device can also contribute to a sense of safety and reassurance for the user, as auditory confirmations of their progress and location can help reduce any uncertainty or confusion. This aspect of the invention can therefore contribute to a more relaxed and confident experience for the patient during their hospital visit. In a preferred design, the wayfinding device includes a circular OLED screen that provides a uniform display of patient-specific information, regardless of the patient's viewing angle. The circular design was chosen as a preference to ensure a consistent and uniform visual experience, making the information on the screen equally clearly visible from different angles. This is particularly beneficial in dynamic environments such as hospitals, where patients may be positioned in different directions and angles relative to the device.The OLED screen can optionally have a diameter between 5 and 10 cm, preferably between 6 and 9 cm, more preferably between 6.5 and 8.5 cm, even more preferably between 7 and 8 cm, and most preferably 7.5 cm. These dimensions ensure that the screen is large enough to clearly display all necessary information, while the device remains compact and portable. The use of an OLED screen also offers advantages in terms of energy efficiency and image quality. OLED technology is known for its deep blacks and high contrast ratio, which promotes the readability of information under various lighting conditions. This is especially useful in poorly lit areas of the hospital, where a bright and clear screen is crucial for patient navigation. BE2024 / 5820 16 Moreover, the OLED screen can be configured in a preferred version to provide adaptive brightness, whereby the screen brightness is automatically adjusted based on the ambient light conditions.This function can be optionally configured to optimize readability while simultaneously minimizing energy consumption, which contributes to a longer battery life of the device. The integration of a circular OLED screen into the wayfinding device further improves user-friendliness and accessibility for patients, making the device a valuable addition to patient care and navigation within the hospital. In a preferred configuration, the wayfinding device includes a user interface with buttons that enable direct interaction with the patient. These buttons can optionally serve to confirm the patient's movement and / or to request assistance when necessary. By promoting such direct interaction, the user experience is significantly improved, leading to higher satisfaction among the device's users. Preferably, these buttons are intuitively placed and easy to operate, so that patients with varying levels of technological proficiency feel comfortable using them.The interface can optionally be equipped with buttons with tactile markings, so that patients with visual impairments can also easily identify and use them. This contributes to the accessibility of the device for a wider range of users.25 In a further preferred design, the user interface can contain buttons that activate various functions, such as pausing route guidance, restarting the route, or calling an emergency service. These functions can optionally be adapted to the specific needs of the hospital or the patient, making the device flexible and versatile in its application. BE2024 / 5820 17 The design of the user interface can preferably be such that it enables clear and direct communication with the device. This can optionally be achieved by the use of visual signals, such as light indicators, that indicate the status of the device, for example whether a button has been successfully pressed or whether an assistance call has been sent.These visual signals can be combined with auditory feedback, such as beeps, to further reinforce interaction. In an even more preferred configuration, the user interface can be integrated with the central OLED display, where the buttons complement the visual information displayed on the screen. This integration creates seamless interaction between the patient and the device, contributing to efficient and trouble-free navigation within the hospital. All of this leads to improved patient flow and increased efficiency of healthcare staff. In a preferred configuration, the wayfinding device can be easily sterilized, contributing to a safe operating environment in the hospital. The device is preferably manufactured from materials resistant to standard sterilization processes, such as autoclavable plastics or stainless steel.Preferably, these materials are chosen to be resistant to both chemical and thermal sterilization methods, making the device versatile for use in various hospital environments. Furthermore, the design of the device can be such that all surfaces are smooth and seamless, which reduces the risk of dirt and bacteria accumulation. This design can further contribute to hygiene by making the device easier to clean without residues remaining in hard-to-reach corners or seams. In a more preferred configuration, the seams and connections of the device can be sealed with silicone or a similar material resistant to sterilization, thereby preventing the ingress of moisture or contaminants. In another preferred configuration, the device can be equipped with a removable housing or protective cover that can be easily detached and sterilized separately.This cover can preferably be made of a flexible material that is resistant to high temperatures and aggressive cleaning agents, making it suitable for repeated use5 without loss of functionality or integrity. The device can also be designed for easy disassembly, so that internal components can be removed if necessary and cleaned or replaced separately. This design can further contribute to the durability10 of the device, as it becomes easier to replace specific parts without having to replace the entire device. Due to these features, the wayfinding device can be used in a hygienic manner in hospital environments, where cleanliness and safety are of the utmost importance15. This contributes to a reduction in the risk of infections and promotes a safe environment for both patients and hospital staff. In a preferred version, the wayfinding device includes an emergency button that allows patients to come into direct contact with hospital staff.This function offers an optional increased sense of safety and reassurance, especially in stressful or urgent circumstances. The help button is preferably integrated in such a way that it is easily accessible to the patient, regardless of their physical or technological abilities. The device can optionally be configured to provide visual or auditory confirmation when the help button is pressed, letting the patient know that their request for help has been received. Furthermore, the communication initiated via the help button can optionally be conducted via a secure communication channel that enables a direct connection with hospital staff. This could be, for example, a direct connection to the reception or to a nurse, depending on the configuration of the device and the needs of the hospital. The speed and efficiency of this communication can optionally be improved by using pre-set messages or by offering the possibility to speak with hospital staff in real time.BE2024 / 5820 19 In a further preferred configuration, the device can also be equipped with a function that transmits the patient's location to hospital staff when the help button is pressed. This can optionally accelerate staff response and help them quickly locate and assist the patient. Location information can be obtained through the integration of BLE technology, which can accurately determine the patient's position within the hospital. The help button can also optionally be programmed to perform certain predefined actions, such as sending an SMS message to a family member or activating an emergency call to the nearest emergency service within the hospital. This provides an extra layer of safety for patients and contributes to an overall improvement of the patient experience within the hospital environment.By integrating the help button into the wayfinding device, this preferred version offers a versatile and user-friendly solution that can be adapted to the specific needs and circumstances of both the patient and the hospital. In a preferred version, the wayfinding device includes a function for two-way audio or video interaction, allowing patients to receive direct guidance. This preferred function can contribute to increased patient confidence in the navigation process within the hospital. Optionally, interaction can take place via an integrated microphone and speaker, allowing patients to communicate intuitively with medical staff. Preferably, the audio or video interaction can be activated by the help button on the device, adding an extra layer of ease of use. In a further preferred version, the video interaction can include a screen connected to the central OLED display, enabling visual communication.This can be particularly useful in situations where verbal communication is insufficient or when the patient requires extravisual cues. Two-way communication can also contribute to a faster response from medical staff, because patient questions and concerns can be addressed in real-time. This can increase the efficiency of care delivery and reassure the patient that they always have access to help when needed. BE2024 / 5820 20 Optionally, the audio or video interaction can be supported by a secure communication system that safeguards the privacy and confidentiality of patient data. In a further preferred implementation, this system can use encryption protocols to comply with other relevant laws and regulations regarding patient data protection.5 In an even further preferred implementation, the interaction functionality can be adapted based on the specific needs of the patient, such as providing translations or adjusting the volume for the hearing impaired.This flexibility can ensure that the device is widely applicable to various patient groups, which increases overall accessibility and user-friendliness. In summary, this preferred version of the wayfinding device offers a versatile and patient-centered solution that can play an important role in improving the navigation experience within hospital environments. In a preferred version, the device can function as an interface that directly transmits the patient's location to hospital staff. This aspect of the invention can contribute to improved collaboration between staff and patients by sharing location information, which can lead to faster and more accurate assistance. The device can be designed to efficiently transmit data via a wireless connection, for example via Bluetooth Low Energy (BLE), allowing hospital staff to receive real-time updates on the patient's position within the facility.25 Preferably, the device is equipped with a system that determines the patient's location by means of a network of beacons strategically placed within the hospital. These beacons can transmit signals that are picked up by the device, enabling accurate positioning. The location data can subsequently be integrated with the hospital information system, which enables a seamless exchange of information between the device and the central systems. BE2024 / 5820 21 In a further preferred configuration, the device can be equipped with a visual interface, such as an OLED display, that not only provides directions but also shows the patient's current location. This can give the patient a sense of orientation and safety, while staff are always aware of the patient's location, which can be particularly useful in emergency situations or when extra assistance is needed.The device can also be equipped with a haptic feedback function that informs the patient about changes in route or location, providing an intuitive and non-invasive way to keep the patient informed of their position. This function can be particularly useful for patients with visual or auditory impairments, as it enables them to receive feedback in a tangible way. Preferred versions of the device may also include a help button which, when pressed, sends a signal to hospital staff to request immediate assistance. This can improve the efficiency of care by ensuring that patients receive the necessary support quickly, while staff are better able to manage their time and resources. Together, these features can contribute to a more patient-centered care environment, in which both the patient and the staff benefit from improved communication and collaboration. EXAMPLES The present invention will now be further explained using the following examples.The current invention is in no way limited to the given examples or to the implementation forms presented in the figures.25 Example 1. A patient arrives at a hospital and identifies himself with his patient ID. At the reception, the appointment details are linked to the wayfinding device. The device immediately displays the name of the attending physician, the room number, and the estimated appointment time on the OLED screen. As the patient walks through the hospital, the device receives signals from BLE beacons that determine the patient's location and automatically adjust the direction directions. The haptic feedback motor vibrates gently to indicate that the patient needs to take a turn, which is particularly useful in busy corridors.35 BE2024 / 5820 22 Example 2. During a sudden change of the appointment location, such as a transfer to another department, the wayfinding device receives a real-time update from the hospital server.The device recalculates the route and provides new directions on the OLED screen, while haptic feedback guides the patient to the new destination. This demonstrates the advantage of the invention in providing up-to-date information and preventing confusion. Example 3. A patient with a visual impairment uses the wayfinding device. The device offers haptic navigation through varying vibration patterns that indicate changes of direction. When the patient approaches his destination, an auditory warning via the loudspeaker indicates that the location has been reached. This example illustrates the intuitive navigation experience that the invention offers. Example 4. In a scenario where a patient needs help, he presses the help button on the device. This activates a direct audio connection to the doctor's office. The patient can ask questions and receives guidance, which increases patient confidence and satisfaction. This example emphasizes the improved patient interaction and immediate staff assistance. Example 5.The device is being tested in various hospital environments. Thanks to safe, sterilization-friendly housing, the device can be easily cleaned after use, which contributes to a safe hospital environment. This example demonstrates the practical benefits of the invention in terms of hygiene and safety. It is assumed that the present invention is not limited to any previously described forms of implementation and that some modifications can be added to the presented manufacturing example without reassessing the attached claims. For example, the invention is described with reference to a hospital environment, but it is clear that the invention can also be applied in other healthcare institutions or large public buildings, such as airports. It is clear that the method according to the invention, as well as the applications thereof, are not limited to the presented examples. BE2024 / 5820 23 The current invention is in no way limited to the described forms in the examples and / or shown in the figures.On the contrary, methods according to the current invention can be realized in many different ways without deviating from the scope of the invention. 5 DETAILED FIGURE DESCRIPTION Figure 1 provides a perspective view of the wayfinding device, emphasizing the rounded, ergonomic shape that strongly resembles a restaurant buzzer. The OLED screen (1) is centrally positioned and designed for easy viewing for patients. The help button (2) is located in an accessible position so that patients can easily ask for help. This view shows the general shape layout of the device, where the patient-friendly ergonomic design is accentuated by the rounded corners and the compact design, which ensures a comfortable grip. The device is designed to be held comfortably, regardless of the patient's age or dexterity. The ergonomic shape and placement of the buttons ensure that users with limited mobility can operate the device effectively.This design is crucial to ensure that the device is widely usable for different patient groups, from the elderly to people with specific needs. Figure 2 shows a detailed front view of the guidance device, showing the different display modes of the OLED screen(1) to guide patients during their visit to the hospital. The OLED screen offers a range of information modes that are dynamically adapted to the needs of the patients and provide essential information for smooth navigation through the hospital. 30 One possible first view display shows the screen appointment details(4), such as the scheduled time of the appointment, the name of the treating physician and the distance to the destination (for example, "10M" for 10 meters). This information helps the patient to go to the correct location on time without confusion. The appointment details are displayed clearly and concisely, so that the patient can quickly35 understand the time schedule and location of the appointment.One possible display mode offers the device navigation instructions (3) by means of arrows that indicate the route to the destination. For example, an upward arrow BE2024 / 5820 24 can represent a straight path to be followed, while a right arrow indicates that the patient must take a right turn. These visual instructions are simple and universally recognizable, making the device suitable for patients with limited reading skills or technological experience. This aspect of the device significantly increases user-friendliness and enables patients to navigate the hospital independently. Another possible display mode informs the patient about specific facilities required for the route, such as an elevator. The message "LIFT-2nd 10th Floor" acts as a kind of directional indicator when a patient needs to take an elevator to reach the correct floor. This effectively helps patients find important locations within the hospital, which improves the overall navigation experience and reduces unnecessary searching.15 In a fourth display mode, the device can display a notification in the event of delays (5), such as "APPOINTMENT-Delay20Min", so that the patient stays informed of any changes to the schedule. This information prevents confusion and enables the patient to adjust his or her expectations without having to wait unnecessarily or worry about the schedule. 20 Another display mode may show when a help function is enabled (6), which is activated when the patient presses the help button (2). In this display mode, the word "HELP" appears on the screen, indicating that the help function is active. This function offers the possibility to establish telephone contact25 with a hospital staff member. Alternatively, the device can send the patient's location to a staff member, so that they can quickly come to the relevant location to find the patient seeking help.These extra support options ensure that the patient feels safe and that help is immediately available when needed, which further increases the reliability and ease of use of the device. These different modes illustrate how the device adapts to provide the patient with all necessary information, which reduces the chance of confusion or missed appointments. The use of simple icons and text makes the device suitable for a wide range of patients, including people with limited reading skills or technological experience. This increases user-friendliness BE2024 / 5820 25 and helps patients navigate the hospital independently. Figure 3 shows an exploded view of the internal components of the wayfinding device, clearly showing the arrangement, composition and interrelationships of the various parts. The device comprises a housing consisting of an enclosing top housing (7) and a back plate (12), which together protect the internal components.The top housing(7) includes a central opening for enclosing the OLED screen(1). The OLED screen(1) is located on the front of the device and is positioned to make the information optimally visible to the patient. This screen serves as the primary visual interface element for displaying navigation instructions and other relevant information. Inside the housing is a control board (8), on which a microcontroller 15 (9) is integrated. The microcontroller is responsible for controlling the various functions of the device, including the visual display on the OLED screen, generating haptic feedback and any communication functions. The control board acts as the central electronic platform for the device. 20 The device features a haptic feedback motor (10), which is connected to the control board (8). This motor provides tactile signals to the user, which can be particularly useful when changing direction or in environments where visual cues may not be sufficient.The haptic feedback offers an additional way to effectively guide users. The power supply is provided by a rechargeable lithium polymer battery (11), which provides continuous power to the microcontroller (9), the OLED screen (1) and the haptic feedback motor (10). This battery is designed for rechargeability and a long lifespan, which increases the portability and independence of the device. The guidance device may include an integrated microphone connected to the control board (8). This microphone can offer the device the ability to facilitate telephone communication, for example to reach hospital staff in situations where the patient needs help. BE2024 / 5820 26 Figure 4 shows an illustration of the use of the guidance device by a patient (13) entering the hospital and receiving guidance to his appointment. Upon entering, the patient (13) goes to the reception, where he or she receives a guidance device that is specifically set to the personal agenda of the patient (13).This configuration can take place in several ways. For example, the patient (13) can scan a barcode or enter a unique code, after which the device is automatically linked to his or her medical appointments for that day. Alternatively, the patient (13) can provide his details at the reception, after which an employee configures a navigation device and hands it to the patient (13), tailored to the personal route and appointments within the hospital. If the patient(13) is exactly on time for the appointment, the OLED screen(1) immediately shows the first direction(3) to the relevant location after receiving the navigation device. In the case of Figure 4, the patient(13) is exactly on time for the appointment, and the device immediately activates navigation to the destination. The OLED screen(1) shows a visual indication, such as an arrow(3), which indicates which route the patient must follow to reach his destination on time.20 For location determination, the device continuously communicates with Bluetooth beacons (14), or possibly with Wi-Fi routers, which are strategically placed in the hospital. These beacons transmit location data to the navigation device, which determines the patient's (13) position in real-time. This allows the device to provide dynamic route instructions that guide the patient (13) directly to the correct department or room. If, for example, the patient (13) needs to change direction or is in the wrong location, the device immediately indicates this by means of visual cues on the OLED screen (1) that are adapted to the new situation. The combination of location tracking and personalization allows the navigation device to follow the patient (13) through the hospital, displaying relevant route instructions or appointment-related information at the appropriate times. This system ensures that the patient (13) can move through the hospital independently and without confusion, with guidance that is precisely tailored to his or her schedule.In addition, the device can display notifications or warnings, for example if there is a delay in the appointment or if the patient (13) needs to go to the appointment.
